ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 495 



or fuscous, the front trochanters, a spot on the knees, a stripe on the middle tibite 

 beneath and the hind femora beneath, yellowish. The front wings, except the basal 

 third and a narrow transverse band on the disk from near the apex of the marginal 

 vein, are fuscous, the basal third and the narrow transverse band being hyaline or 

 whitish. 



Tyjje. — Cat. No. 7662, U. S. N. M. 



Brazil : Chapada ; Bahia (Mr. A. Koebele). 



This is the only species known in this genus with a punctate abdomen. The 

 specimens from Bahia were bred in March, 1883, by Mr. Albert Koebele, from the 

 eggs of an unknown locustid. 



Anastatus UNiFAsciATUs, sp. nov. 



Female. — Length about 5 mm. Dark blue-green, the vertex and disk of the 

 mesonotum more decidedly green ; scape yellow, the flagellum, including the pedi- 

 cel, brown-black, the club with a whitish spot on the oblique truncature ; legs dark 

 brown or fuscous, the front and middle tarsi and joints two to four of hind tarsi be- 

 neath, yellowish-white. Wings much as in A. basalts. 



Brazil : Rio de Janeiro. 



Tribe II. Tanaostigmini. 



Trichencyrtus Ashmead, gen. nov. 



This genus is allied to Tanaostigmodes Ashmead, and resembles it in shape, but 

 the body is not bare, as in that genus, but clothed with short, scale-like, white hairs. 

 It is also easily separated by the difference in the antennse, the scape being subcom- 

 pressed, the funicle joints one to three being wider than long. In Tanaostigmodes 

 the funicle joints are cylindrical and longer than wide. 



Trichencyrtus robustus, sp. nov. 

 (Plate XXXVII., Fig. 5.) 



Female. — Length 2 mm. Robust, peneous black, with metallic bluish reflections 

 in certain lights, the whole body clothed with short, scale-like white hairs, the head 

 with a white band across the lower part of the face and extending on to the cheeks 

 back of the eyes ; there is also another slender white line above this, on each side ; 

 extending from the insertion of each antenna to the eye margin ; the very short 

 pronotum has a triangular white spot on each side ; the front tarsi, or at least more 

 or less beneath, and the short sheaths of the ovipositor, are testaceous. The scape 

 of the antennae is flat, dilated, aeneous black, the flagellum dull black, pubescent, 

 the basal joints wider than long. The wnngs are hyaline, the costal cell broad, the
